Problems solved by technology

[0006] At present, the adhesives for nuclear power mica tapes are all developed on the basis of silicone pressure-sensitive adhesives, which have electrical insulation, high and low temperature resistance, etc., but the disadvantages are poor dryness, stickiness, moisture absorption, and high temperature resistance. and radiation resistance
The resulting mica tape has high cost, low surface wear resistance, poor high temperature and radiation resistance, and low strength and elongation

Abstract

The invention relates to a silicon resin composition for nuclear motor mica tape. The silicon resin is mainly prepared by the following raw materials which comprise, by mass percent, 10-50% of methyl MQ silicon resin, 9-25% of phenyl MQ silicon resin, 5-30% of hydroxyl silicone rubber, 10-40% of phenyl silicone rubber, 40% of organic solvents and 0.005-0.02% of basic catalysts. The nuclear motor mica tape using the silicon resin composition is low in product production cost, high in surface abrasive resistance, good in flame retardant performance, self-extinguishing resistance and insulating performance and resistant to high temperature and radiation, and has sufficient strength and proper ductility.

Description

technical field [0001] The invention relates to a silicone resin composition for nuclear motor mica tapes and uses thereof, in particular to a silicone resin composition for nuclear motor mica tapes, and a binder prepared from the silicone resin composition. A nuclear motor mica tape and a preparation method of the mica tape. Background technique [0002] Mica tape, also known as refractory mica tape, is a kind of refractory insulating material. It can be divided into: mica tape for motor and mica tape for cable. According to the structure, it is divided into: double-sided tape, single-sided tape, three-in-one tape, double-film tape, single-film tape, etc. According to mica, it can be divided into: synthetic mica tape, phlogopite tape, muscovite tape. [0003] Mica tape is a composite insulating material, mainly composed of three materials: dielectric material, reinforcing material, adhesive. [0004] At present, the motor is developing in the direction of high voltage le...
